fix: address PR review — XSS hardening, test fixes, noopener

- Use json_script filter instead of |safe for chart data
- Add rel="noopener noreferrer" to all target="_blank" links
- Gate email date range on both start_date and end_date
- Log notification persistence failures instead of silent pass
- Fix test assertions to match actual view behavior
